AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.

AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.

Forecast Discussion: Thursday, as a low pressure system moves into northern California, light to moderate southeasterly winds will aid pollutant dispersion in Sacramento. However, these winds will also transport pollutants into the region. Therefore, particle levels will be Moderate. Friday and Saturday, moderate southerly winds will weaken over time, gradually inhibiting pollutant dispersion. However, pollutant carryover from day to day will be low. These conditions will result in Good particle levels on Friday and Moderate particle levels on Saturday.
